hat are the advantages of tea vacuum packaging machines
Date：2024-08-27 Categories：Blog
The market like the tea vacuum packaging machines because of shared advantages:
(1) Moisture-proof
The moisture in tea is the medium for biochemical changes in tea. Low moisture content is conducive to the preservation of tea quality. The moisture content in tea should not exceed 5%. 3% is the best for long-term storage. Otherwise, the ascorbic acid in the tea is easy to decompose, and the color, aroma, and taste of the tea will change. Especially at higher temperatures, the rate of deterioration will accelerate. Therefore, when packaging tea vacuum packaging machines, you can choose to use composite films with good moisture-proof properties, such as aluminum foil or aluminum foil vapor-deposited film as the basic material for moisture-proof packaging.
(2) Anti-oxidation
Excessive oxygen content in tea vacuum packaging machines will lead to oxidation and deterioration of certain components in tea. For example, ascorbic acid is easily oxidized to deoxyascorbic acid. And further react with amino acids to form pigments, which deteriorates the taste of tea. Therefore, the oxygen content in tea packaging must be effectively controlled below 1%. In the packaging technology of tea vacuum packaging machines, air filling packaging or vacuum packaging can be used to reduce the presence of oxygen. Vacuum packaging technology is to put tea into a soft film packaging bag with good airtightness. When packaging, the air in the bag is removed to create a certain vacuum degree, and then the bag is sealed. Inflatable packaging technology is to fill in inert gases such as nitrogen while exhausting the air. The purpose is to protect the color, aroma and taste of the tea leaves and maintain their original quality.
(3) Gas barrier
The aroma of tea leaves is very easy to dissipate and is easily affected by external odors, especially the residual solvents in the composite film and the odors decomposed by electric ironing and heat sealing treatments. They will affect the flavor of the tea leaves and affect the aroma of the tea leaves. Therefore, when packaging tea leaves with a tea vacuum packaging machine, it is necessary to avoid the aroma from escaping from the packaging and the absorption of odors from the outside. The packaging material of tea leaves must have a certain gas barrier performance.
(4) High temperature resistance
Temperature is an important factor affecting the quality of tea leaves. The rate of chemical reactions differs by 3 to 5 times for a temperature difference of 10°C. Tea leaves will intensify the oxidation of the substances contained in them at high temperatures, resulting in a rapid reduction of effective substances such as polyphenols and accelerated quality deterioration. The best storage temperature for tea is below 5℃. When the temperature is between 10 and 15℃, the color of tea fades slowly. The color effect can also be maintained well. When the temperature exceeds 25℃, the color of tea changes rapidly. Therefore, tea is suitable for storage at low temperatures.
(5) Shading
Light can promote the oxidation of substances such as chlorophyll and lipids in tea, increase the amount of odor substances such as valeraldehyde and propionaldehyde in tea, and accelerate the aging of tea. Therefore, when packaging tea, the tea vacuum packaging machine must shade the light to prevent chlorophyll, lipids and other components from undergoing photocatalytic reactions. In addition, ultraviolet rays are also an important factor causing tea to deteriorate. To solve this problem, light-shielding packaging technology can be used.
The biggest feature of the external vacuum packaging machine is that it is not limited by the size and volume of the packaging material, and can be packaged in vacuum or nitrogen (or other gases) at will. It has a wide range of applications, high economic benefits, and is very convenient to use. This vacuum packaging machine is suitable for packaging materials such as various composite films such as polyester/polyethylene, nylon/polypropylene, polypropylene/polyethylene, polyester/aluminum foil/polyethylene, nylon/aluminum foil/polyethylene and other composite materials. The items packaged by Dingye tea vacuum packaging machine are anti-mildew, anti-insect, anti-pollution, anti-oxidation, save volume, extend storage period, and ensure the quality of the items.
